About 2 months ago I started dabbling in my spare time building a low-cost, low foot print smart control that will not only monitor my radiant in floor system but also control it.
The system is designed to be VERY low-cost and incredibly tiny making it easy for anyone with a hydronic heating system to control and monitor their hydronic heating system from anywhere in the world.
Two things inspired me to build a Hydronic Smart Control, the first is my love of radiant heating and the second is my passion for the ecobee smart thermostat which is an awesome device. ecobee has inspired me to put my programmer hat on and get the soldering iron out and the result is my very own radiant smart control.
Since my last post I now have my system up and running and monitoring my radiant in floor system. The code is 50% complete and internet monitoring enables me to see what my system is doing at any time but more importantly it gives me the ability to control my system. Features so far;
- No computer required to run the system
- Very small footprint ( fits in your palm of your hand )
- Cloud storage of data through a wifi connection
- Multi zone monitoring
- Multi Zone control ( almost complete )
- Monitoring equipment run time ( almost complete )
The old adage ‘size matters’ means a lot to me with this control. The last photo I posted of the control it was the size of my business card. The new version which I am not ready to share a photo of just yet is now the size of a box of matches and has all the same functionality.
Below you can checkout a screen grab of my online dashboard. I can access my REHAU Radiant in floor system from any smart phone or computer from anywhere in the world. I am currently uploading data on a 5 second interval to the cloud and showing current RAUPanel floor temperature as well as the average temperature over a 24hour period and a graph of the last few hours. ( Edit: Just noticed its saying C and not F for temperature… whoops! That will be fixed shortly! )
For those curious RAUPanel delivers up to 32 BTU’s per square foot at 110 degree water making it one of the most efficient heating systems in the world. With my radiant control I can not only see when the system is running and what the temperatures are and turn it on and off but I can also do some basic performance benchmarks to see how well my system works at different water temperatures and flow rates as well as how quickly my house warms up under those conditions.
My ‘Smart’ Wifi Enabled radiant in floor system is I think a cutting edge advancement to hydronic heating that anyone can afford and use. ( Now if only I could think of a name for it ).
